Ace female, fine, fit and obliging (7)
I believe the answer is:
affable
'obliging' is the definition.
(thesaurus)
'ace female fine fit' is the wordplay.
'ace' becomes 'a'.
'female' becomes 'f' (abbreviation).
'fine' becomes 'f' (abbreviation).
'fit' becomes 'able' ('able' can be similar in meaning to 'fit'**).
'a'+'f'+'f'+'able'='AFFABLE'
'and' is the link.
(Other definitions for affable that I've seen before include "Congenial, easy to walk" , "nice" , "Easy to talk to" , "Showing friendly warmth" , "having easy manners" .)
